Provided is a technology platform configured to provide alerts to real estate consumers and professionals. The foregoing can include an application program (or “app”) executable on a mobile phone, or other electronic device, to process data and generate and output alerts to a user of the device. The alerts can be sent to the app when one or more properties satisfy a user' s criteria for a target property. The technology platform can process user property search criteria related to dynamically changing values of a property or related to qualitative aspects of a property. The app, with the support of a platform, can provide a real-time, location-based real estate property tour through a mobile device. In some forms, the technology platform can pair lead generation capabilities for real estate agents/brokers and/or mortgage brokers/lenders with real estate search functionality and information.
